Jesus never mentioned homosexuality. Actually, the entire Bible is devoid of the word. Nothing - or at least extremely little - was known of homosexuality at that time. The Bible does condemn a lot of things, especially Leviticus is an often used book to condemn homosexuals with. Leviticus however, also condemns shellfish and orders the most gruesome violence toward practically anyone and anything that trespasses the laws - that were arguably just laid down to keep the temple staff 'pure'. For homosexuals that are struggling with the harsh words in the Bible (that actually believe what it says) I would like to say the following:
The Bible is a collection of Books, it is not one. Some books are outdated, like Leviticus. The Bible is not the absolute word of God, it was written by people who were to a degree inspired by God. What is most important is that it gives stories that are concerned with the Christian religion, and tells the story of Jesus Christ. That is all. There is no literal truth - just the story that you can take from the pages of the Bible. Read Samuel 1 & Samuel 2, concentrate on the story of David and Jonathan for comfort. If you are looking for a (more or less) complete investigation of the subject, download "A Letter To Louise", the response by a baptist minister to questions of a dear friend of his family concerning the subject. I would give you the link, but I can't (it'd be deleted again), so here's an alternative:

That's not a real link, right?
Jesus might have been gay, he might not have been. What is certain is that - if he existed and was gay - it would not have been recognized as a natural form of sexuality (they had no clue about this kind of thing) and such feelings or actions would probably have been repressed by Jesus or either have been wiped away from history by the people who assembled and/or reformed the Bible throughout the ages.
